Oneway's scroll chucks provide several powerful and versatile self-centering stock holding functions. Their jaws can expand within a shallow undercut recess to grip the bottom of a bowl securely, or they can tighten around a foot, stub tenon or the end of a spindle. A variety of optional jaw sizes gives these chucks a very wide grip range; they can hold round or square tenons from just 1/4" (with Spigot Jaws) to 15" in diameter with Mega Jumbo Jaws. Standard equipment includes a 1/2" x 1-1/4" Woodworm Screw, whose deep, sharp threads & tapered nose are exceptionally effective. Woodworms are designed to be installed easily and securely in all three chuck models.

Oneway chucks can be used on almost any lathe. Threaded taper-lock mounting adapters, available to fit a wide variety of lathes, center themselves perfectly in the chuck body, which can then be screwed onto your lathe's spindle nose. Two of the most popular sizes, 1"-8 tpi & 1-1/4-8 tpi, are cross-threaded right- & left-hand to work equally well on both inboard and outboard spindles. An adapter is required for mounting Oneway chucks. Extra adapters offer a very economical way to use the same chuck on every lathe you own. Note that Talon and Oneway chucks accept adapters up to 33mm. Only the Stronghold Chuck handles 1-1/2"-8 tpi mounting adapters.

There are three scroll chuck models, Talon, Oneway and Stronghold; your choice can be determined by size and budget. Stronghold is the heavyweight; if you turn large, heavy objects as well as smaller stuff, it's the natural choice. Oneway and Talon chucks have nearly identical capacities; the main difference is that you operate the jaws on the original Oneway chuck with two levers ("tommy bars"), while the Talon, like the Stronghold, offers the convenience of a large T-handled single chuck key. Each chuck is equipped with #2 profile jaws, a 1/2" x 1-1/4" Woodworm screw, operating key or levers, and a thorough instruction booklet. Order the adapter(s) of your choice separately.

This is the chuck ONLY! A mounting adapter (sold separately)is required to fit your lathe.
